Abstract

L'invention concerne une broche porte-outil. Un arbre de broche est monté sur un palier hydrostatique avec des portées de palier recevant dans des chambres un fluide sous pression et coopérant avec des portées d'appui. Des organes sont prévus 61, 47, par l'intermédiaire desquels l'arbre de broche 7 subit une poussée hydraulique dirigée dans le sens allant de la portée d'appui de plus gros diamètre à la portée d'appui de plus petit diamètre, poussée asservie de façon prédéterminée à la pression du fluide hydraulique amené aux chambres de pression 14, 16.
